The flag of the city of Borås, Sweden, is red with two old-fashioned
wool scissors argent, the sinister one upright and the dexter one
inverted.
It is often flown fron City Hall, etc.Per YP Hansson, 30 September 2006

The Coat of Arms exists since at
least the late 17th century, as shown in this 1700 engraving, showing
only minor variants in its details.
At
Ralf’s site a
large
image of the arms, from which I made the attached banner of arms; I’m not sure if this
exact design is used in actual flags. The reported photo shows a slightly
different design, with thin, dark detail and contour lines.António Martins-Tuválkin, 27 September 2010
